Application led February 21, 1.918. Serial No. 218,575.

To all whom t may conce/mt Be it known that I, HAROLD B. CimNsHAw, a citizen of the United States or America, and resident of Boston, in the county of' Su'olk and State of Massachusetts, have in.- vented new and useful improvements in Receptacles, of which the following is a speciication.

This invention relates to receptacles and4 more particularly to paper receptacles designed for use as sputum cups.

The principal object ol the invention is to produce a ilask which can be cheaply and easily constructed, which will hold rigidly together after being assembled, which may be formed from asingle piece of material including thecover, and which has an iinproved tapered or wedge-shaped locking` means by which the cover may be quickly opened or closed and by which the cover is held firmly closed when locked.

Other objects oit the invention will be apparent from the following description and the accompanying drawings, in which- Figure 1 isa plan view of the blank from which the receptacle is constructed;

Figure 2 is a front elevation of the recepf tacle when closed and locked;

Figure 3 is a vertical central longitudinal ection of the receptacle on line 3 3 ci Figure 4, is a vertical central transverse section of the receptacle with the cover raised; y

Figure 5 is a front elevation oi a modi` lied receptacle showing the cover practically raised; and

Figure 6 is a front elevation of the moditied receptacle of Fig. 5, showing the cover closed and locked.

The particular embodiment o1 my invention illustrated in Figs. 1 to 4 comprises a rectangular receptacle having a bottom 1, a front 2, a back 3, sides 4 and 5, gusset corners 6, 7, 8 and 9, folding rims 10 and 11 at the front and back, folding rims 12, 13, 14 and 15 at the sides, extensions 16 and 17 at the sides having locking tabs 18 and 19, a cover 2O connecting integrally with the cup by means of a neck 21, and a cover lock 22 adapted to cooperate with an opening 23, in the rim 10 to lock the covei1 in closed position.

As illustrated in 1 the receptacle, including the cover, is preferably formed from a single piece or blank stamped or otherin Figs. 2, 8 and 4. The

tacle comprises the cover lock 22.

wise cut into theform shown from sheet paper, paperoid, leatl'ieroid, or the like. In forming the receptacle the blank is folded along the dash Llines into the shape shown rims 11.*12-13 and 10-14`15 are .first folded oijitwardly through 180. The front 2, back and sides 4 and 5 are then bent into an upright position. The cover lgussets G-S and 7-9 are folded inwardly along the outside of `the sides 4 and 5. The extensions 16 and l? are folded downwardly over the rims 12-14 and 13-15 and over the folded gussets `at each side and the locking tabs 1S and 19 are folded upwardly under the folded gussets. The cover is then folded upwardly and bent over the rear edge of the cup and the cover lock 22 is inserted through the opening 23.

A cardinal feature of my improved recep. Ilhis unique lock conuirises a tab which is somewhat wider, in a i ion intermediate its ends than the cooperating slot, and which tapers gradually toward each end. The inner end preferably of substantially the same width as the slot and the outer end is preferably considerably narrower than the slot. When shaped in this particularmanner the tab is readily inserted through the slot, by virtue of the narrow tapered outer end, and when inserted is tightly held in position by virtue of the tapered inne-r end wedging in the slot. As the tab is passed through the slot it is flexed to an extent depending upon the excess width of the tab and after passing through the slot the tab straightens out into the position sliown in F 2 where it is closely confined. lVhen it is desired to open the receptacle the cover is pulled upwardly and, by virtue of ythe tapered inner end of the tab, the tab is automatically tiered an amount siilliicient to permit it to pass out from the slot. Thus Kthe tab is not only held snugly in locked. position when locked but it is automatically flexed by the opposite ta pers of the ends both when being inserted and when being withdrawn so that it is only necessary to press the cover and cup together or pull them apart to lock or unlock the cover.

In Figs. 5 and 6 is illustrated a receptacle 24 in which the opening 25 for the cover tab 26 is formed in the front 27 of the bor instead of in a folded rim as in Figs. 1 to 4. Moreover, instead of having substantially the saine width throughout as in Figs.

l to et the slot 25 in Figs. 5 and 6 is tapered in the saine direct-ion as the inner end of the tab. The upper end of the opening has substantially the same width as the corresponding section of the tab, and the tab tapers more rapidly than the openingso that the 'tab is lirmly held in the opening alter being inserted thereinto as in Figs. l to fi. However, by virtue ot the downward flare of the opening the tab need not be flexed so much when passed through the opening as when the opening is of substantially uniform width.

ln inserting or withdrawing either the tab 22 or the tab 26 the automatic flexing above referred to may be supplemented.y itt desired, by pressing the opposite sides of the tab to-` gether or in other suitable manner.

iVhat l claim is 1- l. A receptacle formed of a single piece of sheet material tolded into the shape of a rectangular cup comprising front, rear and side portions, gussets between the front and side Vportions and between the rear and side portions, said gussets being folded along the side portions, an extension on each oi' said sides having locking tabs folded over and then under the adjacent folded gussets and thereby lock the gussets, front, back and sides in lixed position7 rims joining the upper edges of said front and back and the gussets adjacent thereto and folding downwardly alongthe outer sides of .said front and back, a cover, a neck joining said cover to the lower edge of said back rim7 said frontriin having a slot therein, and a tongue on the forward edge oi' said cover adapted to Fit into said slot.

A blank tor paper receptacles comprising a body portion provided with a plurality of fold lines designating a bottom section, front, back and side sections radiating therefrom, gusset corner sections between the said front.y back and side sectionfra cover portion extending upwardly 'troni the said back section, a longitudinal rim portion extending along the said back section and the adjacent gusset sections, a neck portion connecting' the said longitiulinal rim section and the cover portion, a longitudinal perforated rini portion extending along the said Jfront section andthe adjacent gusset sections, and an extension on each side section provided with a neck portion connecting 'the said extension with an elongate tab parallel thereto.
